SiteLink



 

The Liebert SiteLink communication interface allows communications between your existing building management system and Liebert environmental, power and uninterruptible power supply products via Modbus or BACnet. The Sitelink modules are available in 12 port and 4 port configurations (i.e. 1 port per/Liebert Unit, 12 Liebert units per/Sitelink module maximum).

Modbus - A SiteLink module is configured to act as a slave device on a common network. This common network can be point-to-point over EIA-232, where one master communicates to on slave device or in a multi-drop configuration over EIA-485, where multiple slaves reside on a common wire or loop. The SiteLink module supports both Modbus RTU (Remote Terminal Unit) and ASCII (American Standard Code for Information Interchange) transmission modes.

BACnet - The SiteLink module provides a BACnet Point-to-Point communications exchange between proprietary Liebert equipment to other BACnet compliant devices. The connection to the SiteLink module is via a configurable serial EIA-232 or multi-drop EIA-485 port.
